15 Multicast Video Traffic Flow: Failover Simulation Traffic flows are rerouted post simulation. Blue: Normal route Dotted: Simulated route due to failure. BRKNMS Cisco and/or its affiliates. All rights reserved. Cisco Public 15

16 Benefits Increase Profitability by reducing call center and truck roll OpEx Reliable Service Experience Troubleshoot traffic flow for an event BRKNMS Cisco and/or its affiliates. All rights reserved. Cisco Public 16

17 Capacity Planning

18 Capacity Planning: Circuit failures simulation Business As Usual Case 1 Case 2 Case 1 Fail Peer3- Market3 Core2 Case 2 Fail Peer1- Market4 Core1 Failure of a circuit results into traffic reroute and updates traffic on new routes. Plan for augmenting all impacted circuit Red: +90% traffic Pink:+100% traffic BRKNMS Cisco and/or its affiliates. All rights reserved. Cisco Public 18

19 Capacity Planning: Adding route Augment Add a route Case 1 Case 2 Add a route bisecting ring. Evaluate cost for augmenting multiple circuit (previous scenario) vs adding one. Augment BRKNMS Cisco and/or its affiliates. All rights reserved. Cisco Public 19

20 Benefits Increase profitability by reducing CapEx with modeling and cost analysis Plan for capacity and network evolution Simulate what if scenario BRKNMS Cisco and/or its affiliates. All rights reserved. Cisco Public 20

21 Planning Shifting Traffic

22 Shifting Traffic 26 Gbps of traffic was identified through peering opportunity. BRKNMS Cisco and/or its affiliates. All rights reserved. Cisco Public 22

23 Shifting Traffic Simulation Create a virtual node, set the source of demands to that node Evaluate primary route and capacity Virtual Node BRKNMS Cisco and/or its affiliates. All rights reserved. Cisco Public 23

24 Shifting Traffic Failover Simulation Primary route failure simulated. Backbone flows demands are within operational guidance. Reroute creates metro demands that exceed capacity. Augmentation required. BRKNMS Cisco and/or its affiliates. All rights reserved. Cisco Public 24

25 Benefits Increase profitability by reducing Transit IP OpEx Improved throughput, reduce latency Ownership BRKNMS Cisco and/or its affiliates. All rights reserved. Cisco Public 25

26 Operations: Network maintenance

27 Network Maintenance: Route Highlighted route is registering packet loss. Maintenance options: Clean fibers or replace interface. Simulate route loss. BRKNMS Cisco and/or its affiliates. All rights reserved. Cisco Public 27

28 Network Maintenance: Route Review traffic reroute. Traffic flows via dotted line reflect no impact due to simulated route loss BRKNMS Cisco and/or its affiliates. All rights reserved. Cisco Public 28

29 Network maintenance: Site Node Business as usual: Review traffic demands on interfaces through common node in Core1. BRKNMS Cisco and/or its affiliates. All rights reserved. Cisco Public 29

30 Network maintenance: simulated node failure & traffic reroute Demands shifted to alternate routes. Capacity impact and flows across alternate routes are simulated. Site14 has two circuits in a single route No service impact to take node down BRKNMS Cisco and/or its affiliates. All rights reserved. Cisco Public 30
